Question : Directions: A tap can fill up a tank of 1250 litres in 4 hours, whereas another tap can fill the same tank in 8 hours. An outlet tap can empty that tank in 6 hours. If all three taps are opened simultaneously, then how much time will it take to fill the tank?
Option 1: 4.2 Hours
Option 2: 5 Hours
Option 3: 4.5 Hours
Option 4: 4.8 Hours
Correct Answer: 4.8 Hours
Solution : Time taken by tap A to fill the tank = 4 hours Tank filled by tap 1 in one hour = 1/4 part of the tank Time taken by tap B to fill the tank = 8 hours Tank filled by tap 2 in one hour = 1/8 part of the tank Time taken by tap C to empty the tank = 6 hours Tank emptied by tap 3 in one hour = 1/6 part of the tank So, the part of the tank filled in one hour when all three taps are opened simultaneously = 1/4 + 1/8 – 1/6 = (6 + 3 – 4)/ 24 = 5/24 Thus, time taken by 3 taps to fill the tank = 24/5 = 4.8 hours
So, the time taken by three taps to fill the tank is 4.8 hours. Hence, the fourth option is correct.

The pattern can be observed running horizontally along the rows. Row 1: (182 × 2) ÷ 26 = 364 ÷ 26 = 14 Row 2: (192 × 2) ÷ 16 = 384 ÷ 16 = 24 Row 3: (187 × 2) ÷ 22 = 374 ÷ 22 = 17
So, 17 is the missing number. Hence, the fourth option is correct.

Question : In a showroom, the price of a washing machine is Rs. 65,000. The customer gets a cash discount of Rs. 2,000 and gets a scratch card promising a percentage discount of 10% to 15%. Determine the difference between the least and the maximum selling prices of the washing machine.
Option 1: Rs. 3,150
Option 2: Rs. 3,570
Option 3: Rs. 3,200
Option 4: Rs. 3,650
Correct Answer: Rs. 3,150
Solution : Here, the price of a washing machine is Rs. 65,000 and the discount is Rs. 2,000. Price of washing machine after cash discount = Rs. (65,000 – 2,000) = Rs. 63,000 Now, a percentage discount of 10% to 15% is given. We know, Selling price = $\frac{100-\text{Discount}\ \%}{100}×$ cost price Maximum selling price of washing machine = $63000 \times \frac{90}{100}$ = Rs. 56,700 Least selling price of washing machine = $63000 \times \frac{85}{100}$ = Rs. 53,550 $\therefore$ Difference = Rs. 56,700 – Rs. 53,550 = Rs. 3,150 Hence, the correct answer is Rs. 3,150.

Option 3: $\frac{5}{2}$
Option 4: $\frac{5}{3}$
Correct Answer: $\frac{5}{3}$
Solution : Given: $2A=3B$ ⇒ $\frac{A}{B}=\frac{3}{2}$ Let, $A=3k,B=2k$ $\frac{A+B}{A}=\frac{3k+2k}{3k}=\frac{5}{3}$ Hence, the correct answer is $\frac{5}{3}$.
